Your enemies are many in Mazer Blazer. And all are out to get you one way or another. But you have your trusty lazer to zap them to prevent them from invading your base located in the center. Protect it with a forcefield by shooting out the four flashing blocks and then zap away, clearing the screen of enemies. Get them at the outer limits of the base for the biggest points. Avoid the destroying walls and get them before they can destroy them for bigger bonus points. Your enemies abound in the cosmic Mazer Blazer!
